Seeing alpha-centavr.cc blank pop-ups shortly after Windows starts – often tied to mshta.exe – can mean an unwanted script is trying to reach a remote server. Because it blends into ordinary system activity, built-in scans sometimes report “nothing found” even while the behavior keeps returning.
Mshta.exe is a Microsoft component that can launch small desktop apps built with web code. That flexibility is useful for some utilities, but it’s also a favorite mask for attackers. The file should live in System32; if it shows up elsewhere, treat it like a stranger wearing its name tag.

How to Remove Alpha-centavr.cc Manually
If the browser shows “Managed by your organization,” a policy is forcing specific options and a standard reset often won’t clear them. The next tasks are meant to locate and remove the entries that let Alpha-centavr.cc reapply settings. Work slowly, delete only what you verify, and keep short notes so you can reverse changes if needed.
1. Identify Active Alpha-centavr.cc Browser Policies
- 1.1
Open the built-in policy page to check for rules that may have been added by Alpha-centavr.cc.
In Chrome: chrome://policy
In Edge: edge://policy
Let the list populate, then review unknown entries; use Reload policies to refresh or export for reference. - 1.2Check each policy for random-looking identifiers, odd URLs, or values that don’t match your setup.
Write down anything suspicious so you can match it to folders or extension IDs later.
Copy the policy Name and Value exactly – they often point to the key or path you need to remove. - 1.3Open the browser’s Extensions page and enable Developer mode.
This shows the extension IDs and install paths needed for a clean removal.
Save each suspicious ID in a text file so you can match it to folders on disk. - 1.4If Extensions won’t open or is greyed out, switch to File Explorer instead.
Working from the profile folder lets you continue even when the browser UI is blocked.
Turn on View > Show > Hidden items so the AppData folders are visible. - 1.5
In File Explorer, open:
C:\Users[Your Username]\AppData\Local\Google\Chrome\User Data\Default\Extensions
Each subfolder name is an extension ID; match it to your notes, avoid deleting known-good folders, and copy the folder to the desktop as a quick backup before removal. - 1.6
Other Chromium-based browsers (for example Brave or Opera) store extensions under a similar AppData structure.
Confirm the extension ID and location before deleting any folder linked to an unwanted add-on.
Use the browser’s About page to verify it’s fully closed so files unlock for removal. - 1.7After deleting the suspicious folder, return to Extensions with Developer mode still enabled.
Confirm the extension is gone; if it reappears, repeat the cleanup and look for leftovers that restore it.
Select Update in Developer mode to refresh the list and catch silent reinstalls.
Remove Alpha-centavr.cc Browser Policies from Windows
Browser policy settings can be stored in the Windows Registry, and careless edits can break apps or even login flows. Focus only on entries that clearly connect to Alpha-centavr.cc, delete exact matches, and leave everything else alone. This removes the policy hooks that survive browser resets while keeping normal settings intact.
2. Remove Alpha-centavr.cc Policy Keys from the Registry
- 2.1Press Win + R, type regedit, and press Enter to open Registry Editor and locate policy keys linked to Alpha-centavr.cc.
Before you edit anything, go to File > Export and create a full registry backup.
Select All under Export range and save the file in Documents or another easy-to-find folder. - 2.2Use Ctrl + F or Edit > Find to search for the policy names you noted or the extension IDs you copied earlier.
Click Find Next and delete only exact matches that clearly belong to the unwanted settings.
Press F3 until no related values remain under HKCU and HKLM. - 2.3
If a key won’t delete, right-click it, choose Permissions, then Advanced.
Next to Owner, click Change, type Everyone, select Check Names, and confirm with OK.
Give Full Control to Administrators and Users so the key and its subkeys can be removed. - 2.4
After you take ownership, tick Replace owner on subcontainers and objects and Replace all child object permission entries.
Click Apply, then OK, Reboot, and see whether the Managed by your organization banner still shows.
If it’s gone, open regedit again and repeat your searches to confirm the values did not return.
Even when the obvious policy keys are gone, a scheduled task, service, or leftover component can recreate the same forced settings after a restart. The options below focus on clearing what still triggers Alpha-centavr.cc without doing a broad reset. If the managed banner returns, work through each item and retest.
